Definitions
- the present invention relates to a device for carrying out processing operations on a workpiece by means of a laser in circumstances when it is not practicable to rotate the workpiece to present different portions of its surface to the laser beam to be operated upon.
- a laser processing apparatus comprising, a focusing head which is mounted on a carriage which is adapted to follow a closed path around a position at which a stationary workpiece to be processed by the laser beam may be placed whilst maintaining the laser beam at normal incidence to the workpiece and bringing it to a focus at the surface of the workpiece, a flexible laser beam guide connecting the focusing head to a stationary laser beam guide, the flexible laser beam guide including at least three optical elbow joints each having an angular movement of more than two hundred and seventy degrees and means for reflecting the laser beam from one optical elbow joint to another and thence to the focusing head, a first of the optical elbow joints being associated with the focusing head, a second of the optical elbow joints being associated with the fixed laser beam guide and the third optical elbow joint being intermediate the first and second optical elbow joints and separated from them by distances such that the focusing head can traverse more than a full circuit around the workpiece without the flexible beam guide coming into contact with the workpiece.
- the second optical elbow joint is provided with a rotational capability about an axis which is coincident with that of the portion of the fixed laser beam guide to which it is attached, and the focusing head carriage is constrained to move on a track which is mounted on a single axis gimbal frame which is pivoted about the same axis thus enabling the laser beam to act on a workpiece which has its axis at any orientation in a plane at right angles to the gimbal axis.
- an orbital laser welder/cutter consists of a focusing head 1 which is mounted on a carriage 2 which runs on a track 3 which surrounds a hole 4 in a base plate 5.
- the base plate 5 is in turn mounted on trunnions 6 which form part of a supporting structure 7.
- the supporting structure 7 acts as a single axis gimbal frame.
- the focusing head 1 is fixed to the carriage 2 in a position such that a radial alignment of the focusing head 1 is maintained as the carriage 2 moves around the track 3.
- a flexible laser beam guide, shown generally by the numeral 8 connects the focusing head 1 to a fixed laser beam guide 9.
- the fixed portion of the laser beam guide 9 passes through the centre of one of the trunnions 6.
- the flexible laser beam guide 8 is provided with an articulated outer casing 10.
- the flexible laser beam guide 8 includes three elbow joints 11, 12 and 13.
- the elbow joint 11 conveys light to the focusing head 1, the elbow joint 12 connects the flexible laser beam guide 8 to the fixed laser beam guide 9, and the elbow joint 13 is intermediate the other two elbow joints.
- Corresponding articulation is provided in the outer casing 10.
- the elbow joints 11, 12 and 13 will be described in more detail later.
- Each elbow joint is universal in its action with an angular movement of more than 270°.
- the axis of rotation of the elbow joint 11 perpendicular to the plane of the base plate 5 should move around a circle of radius 70 units centred on the hole 4 in the base plate 5, the corresponding axis of rotation of the elbow joint 12 should be 110 units from the centre of the hole 4 in the base plate 5, and the separations between the corresponding axes of rotation of the elbow joints 11 and 13 and 12 and 13, respectively, should be 132.9 and 92.9 units.
- FIG. 2 The action of a flexible beam guide 8 with such dimensions is illustrated in Figure 2. As the action of the flexible laser beam guide 8 is symmetrical, only half a complete circuit is shown. The motion starts from the position labelled I, proceeds to position II, and thence to position III. The remaining part of the motion is a mirror image of that shown. The starting position is such that the optic axis 21 of the focusing head 1 rotates through some 370° in a complete cycle of operation, so ensuring the complete joining or severance of sections of piping 20.
- Figure 3 shows the construction of one form of elbow joint.
- an input mirror 31 and an output mirror 32 are mounted in input and output parts 33 and 34, respectively, of the elbow joint.
- the input and output parts 33 and 34 of the elbow joint are joined by a short intermediate section 35 which incorporates a journal bearing 36 such that the input and output parts 33 and 34 of the elbow joint can rotate relative to each other about the longitudinal axis 35' of the intermediate section 35 of the elbow joint.
- the input part 33 of the elbow joint is joined to its associated section 37 of the laser beam guide by means of a joint which includes another journal bearing 38.
- the bearing 38 enables the input part 33 of the elbow joint to rotate about the longitudinal axis 37' of the section 37 of the laser beam guide.
- the output part 34 of the elbow joint is joined rigidly to its associated section 39 of the laser beam guide.
- the bearings 36 and 38 provide for a universal action of the elbow joint.
- the mirrors 31 and 32 are so positioned that when the longitudinal axes 37 1 , 35' and 39' of the sections 37, 35 and 39 of the laser beam guide are co-planar, the mirrors 31 and 32 are parallel and at an angle of 45° to the longitudinal axes 37 1 , 35' and 39' of the sections 37, 35 and 39 of the laser beam guide. Thus these axes form the optic axis of the optical system formed by the mirrors 31 and 32.
- a beam 40 of laser radiation entering the elbow joint along the axis 37 1 of the section 37 of the laser beam guide will leave the elbow joint along the axis 39'. of the section 39 of the laser beam guide whatever the relative positions of the input and output parts 33 and 34 of the elbow joint.
- Figure 4 shows a form of elbow joint in which these conditions can be relaxed.
- the general principles of construction are the same as those of the elbow joint which has been described already so the construction of the elbow joint will not be described in detail again, and those components which are similar to those in the elbow joint already described are given the same reference numbers.
- the two forms of the elbow joint differ in that instead of the mirrors 31 and 32 being accurately pre-aligned, one of them, in the illustration the output mirror 32 although it can be either of them, is mounted so that it can be moved about two perpendicular axes, and there is provided a servo mechanism 41 which maintains the alignment of the mirrors required to ensure that the laser beam 40 leaving the elbow joint does so along the axis 39' of the section 39 of the laser beam guide whatever the relative positions of the input and output parts 33 and 34 of the elbow joint.
- the servo mechanism 41 any convenient form of laser beam position sensor can be used such as a diaphragm 42 divided into quadrants 43 each of which has a temperature sensor 44 associated with it.
- one of the sections of the flexible laser beam guide 8 can be provided with a telescopic joint.
- the required orientation of the operating laser beam in relation to the piping 20 can be maintained whatever the orientation of the axis of the piping 20 in a plane perpendicular to the axis of rotation of the base plate 5.
